I'm having trouble with Google Music Manager too but for the other way around, i.e. Uploading. I've set it to automatically upload but after the initial upload, it refuses to acknowledge that I've added anything else. I've restarted the app, restarted the machine, nothing!

I don't dare remove the app and re-install because I know for a fact the database is local to the app and therefore it tries to upload everything from. Scratch again and Google Music doesn't handle duplicates.

well I let it run last night to see what happened and it downloaded all the tracks again - just checked and it stated it had 1 track to re-download but when done that it wanted to download them all again

Quote:I understand how frustrating this issue can be but unfortunately the Google Play Music Manager will always re-download the entire content of your library. I'm not sure why it's designed like this but it's working as intended.

So the software which is supposed to manage your music, can't actually perform the correct job and constantly wants to re-download all your music, thus wasting bandwidth for the end-user
